The Keysight (formerly Agilent) DSA91304A is a 13 GHz high-performance Digital Signal Analyzer (DSA) belonging to the Infiniium 90000A Series. Designed for rigorous signal integrity applications, debugging, and compliance testing, this model features 40 GSa/s maximum sample rates across all four analog channels and an industry-leading low noise floor. As a 'DSA' variant, it comes standard with 20 Mpts of acquisition memory per channel, EZJIT+ jitter analysis (including RJ/DJ separation), Serial Data Analysis (SDA) with clock recovery, real-time eye diagrams, and noise reduction software.
